Background: The purpose of this study is to determine the frequency of underlying hematological disorders as the cause of acute adolescent menorrhagia.Methods: The records of 25 patients that were hospitalized with acute adolescent menorrhagia in the Obstetrics and Gynecology Department of Cerrahpaşa Medical School of Istanbul University between 1988 and 1995 were analyzed.Results: The mean age of the patients was 13.9 +/- 1.6 (SD) years. A hematological abnormality that caused bleeding diathesis and acute menorrhagia was diagnosed in 7 of the 25 patients (28%). There were four cases of immune thrombocytopenic purpura, two cases of Van Willebrand disease and one case of acute promyelocytic leukemia. All seven patients with a coagulation disorder required blood transfusions and the mean hemoglobin level at presentation was 6.2 g/dl. [ABSTRACT FROM AUTHOR]

The purpose of this study was to determine the prevalence and antimicrobial resistance of Mobiluncus species isolated from specimens collected from Turkish women with gynaecological infections. Mobiluncus species were isolated on enriched Schaedler agar and RLK agar plates under anaerobic conditions. The MICs of various antibiotics were evaluated using an agar dilution procedure. The prevalence of Mobiluncus species isolated from vulvo-vaginal abscesses, endometrial smears, salpingitis and bacterial vaginosis was 2%, 4.7%, 3.8% and 49%, respectively. Mobiluncus isolates were only resistant to metronidazole (81% resistance). The isolation rate of M. curtisii was higher than M. mulieris in Turkish women with bacterial vaginosis, vulvo-vaginal abscesses, endometritis or salpingitis.

Objective: To determine the perinatal and maternal outcome of the macrosomic infants., Study Design: A case-control, retrospective study is performed in the Department of Gynecology and Obstetrics, Istanbul University Cerrahpasa Medical Faculty, between 1988-1992. The maternal and neonatal records of infants with birthweight of at least 4000g (n=1000) were reviewed. Another 1000 cases amongst the newborns delivered in the same period between 2500 and 3999g formed the control group. The obstetrical outcome variables of the groups including mode of delivery and the incidence of maternal and perinatal complications were compared., Results: A total of 16,112 deliveries occurred during the study period. The rate of macrosomic deliveries was 6.21% and the rate of the deliveries (4500g or heavier) was 1.04%. The mean birthweight of the study group was 4272+/-239 and 3277+/-316g of the control group (P<0.001). While the cesarean section rate was 28.8% for the study group and it was 16.6% for the control group (P<0.001). In the study group, 17 cases of brachial plexus palsy (2.4%), 16 cases of clavicular fracture (2.3%) and one case of humeral fracture were observed (P<0.001). The rate of perinatal mortality was 0.8% in the study group. No perinatal mortality was recorded in the control group. There were 14 cases (1.4%)of asphyxia related to delivery in the study group (P<0.01). The rate of maternal complications, were significantly higher in the study group (P<0.01)., Conclusion: The macrosomic infants are in increased risk for birth trauma and asphyxia. The risk of birth trauma for the infants weighing 4500g or more is even greater.

To investigate the effect of leukocytospermia on standard semen analysis and sperm function tests such as acrosome reaction, hypoosmotic swelling, antisperm antibody binding and cervical mucus penetration, a prospective clinical study was performed. Two hundred and nineteen male infertility patients undergoing investigation and treatment were included in the study. There was a significant association between acrosome reaction positivity and leukocytospermia according to WHO (World Health Organization) criteria. Increased hypoosmotic swelling test score, higher sperm concentration and enhanced acrosome reaction were closely related to leukocytospermia. When the patients were divided into subgroups according to seminal leukocyte concentrations, acrosome reaction and hypoosmotic swelling were observed to be higher in semen samples with higher leukocyte concentrations compared to those with low seminal leukocyte concentration. In addition, higher sperm concentrations were observed in semen samples with increased leukocyte levels compared to semen samples with low leukocyte levels. These results suggest that leukocytospermia may have a favorable effect on some sperm functions at seminal leukocyte concentrations between 1 and 3x10(6)/ml.

In the present study we investigated the accuracy of Shepard's formula in the sonographic diagnosis of macrosomic fetus of non-diabetic pregnant women. Three hundred and eighty-one macrosomic and 450 appropriate for gestational age (AGA) fetuses born to non-diabetic mothers between 37-42 weeks of gestation were included in the study. Ultrasonographic fetal weight estimation within two days of delivery was made using Shepard's formula in all patients. The estimated fetal weights were compared with the actual birth weights of the same subjects. We did not observe any macrosomic newborn birth in pregnant women with 3200 g or less fetal weight estimation. However, in patients with 3400-3499 g fetal weight estimation, a statistically significant increase in macrosomic newborn birth was observed. Only 3.2% of newborns having actual birth weights greater than or equal to 4000 g had sonographic birth weight estimation less than 4000 g. Accuracy of weight estimations using the Shepard's formula was found to be low in macrosomic fetus. On the other hand, increased incidence of macrosomic newborn birth was observed in subjects with ultrasonographic fetal weight estimations above 3400 g and this level may be useful as a cut-off value for prediction of macrosomic fetus in non-diabetic pregnant women.

The prognostic predictive value of maternal serum CA125 measurement was investigated in 25 cases of threatened abortion. The women were non-smoker, had a ultrasonographically verified viable single fetus, and the gestational ages ranged from 7 to 12 weeks. Twenty-five healty pregnant women, with the same characteristics were used as the control group. The overall abortion rate was found to be 20% (5/25) in the study group. In serial measurements the mean serum CA125 level of the patients with an unfavorable pregnancy outcome was significantly higher than that of the patients with a favorable outcome. When the cut-off level of maternal serum CA125 was taken as > 65 U/ml in the first and > 60 U/ml in the second measurements of the study group, the risk of termination of the pregnancy by spontaneous abortion was 83.3% in the patients with elevated serum CA125 levels. No statistically significant difference was observed with respect to the duration of vaginal bleeding between the aborters and the patients with a favorable outcome. Nevertheless, when vaginal bleeding had been present for 3 days or more and there was high maternal serum CA125 activity, the abortion risk was found to be 100% (3/3). These findings suggest that the maternal serum CA125 measurement in threatened abortion can be useful to determine the extent of decidual destruction which is directly related to the outcome of pregnancy.

The aim of the study was to evaluate the effect of the introduction of fetal heart rate monitoring on perinatal mortality rates in high-risk pregnancies. Results were compared with the perinatal mortality rates published previously from our clinics. The study group consisted of 2165 high-risk pregnant patients. The perinatal mortality rate in the study group was 28.6%, and the corrected rate 15.9%. The rates were significantly lower in comparison with the total perinatal mortality rates in former years. We are convinced that fetal heart-rate monitoring resulted in a significant decrease in the perinatal mortality rate. Although the increased use of fetal monitoring cannot reduce perinatal mortality resulting from problems such as genetic disorders, this study shows improved outcomes for many high-risk conditions, in particular postmature pregnancies.

The predictive value of fetal heart-rate monitoring on fetal well-being was studied in 2165 high-risk pregnancies. 1883 reactive nonstress test (NST) patterns and 278 nonreactive NST patterns and 4 cases of sinusoidal pattern were obtained. Oxytocin challenge test (OCT) was applied to 263 nonreactive cases. OCT was not applied to 15 cases out of 278 nonreactive NST cases, because of placenta previa, abruptio placenta and previous cesarean section. There were 155 cases with negative OCT, 84 cases with positive OCT and 24 cases with equivocal, prolonged or severe variable decelerations. Sensitivity and specificity were for NST 50 and 88% and for OCT 60 and 67%. The positive and negative predictive values were 11 and 98% for NST and 18 and 93% for OCT. It is concluded that the reactive nonstress test is a reliable test for good outcome but a positive oxytocin challenge test is not a reliable test for poor outcome. Additional procedures are necessary such as assessment of fetal growth, doppler velocity waveforms and fetal biophysical profile to avoid unnecessary obstetric interventions and to reach good fetal outcome.
